We handle furnace, heat pump, and gas heating repair across the San Gabriel Valley and will find you the earliest opening on the schedule. Phones are answered 24/7 — service runs during open hours, Mon–Fri 7 AM–6 PM and Sat 9 AM–2 PM.

Before you call: check the thermostat is set to HEAT and the temperature is above current room temp; check that the furnace switch (looks like a light switch near the unit) is ON; check the breaker; and check the air filter isn’t completely clogged. If all of those are fine, call us — common culprits are a failed ignitor, a flame sensor that needs cleaning, or a draft inducer motor.

Most furnace repairs land between $200 and $600 — ignitor, flame sensor, blower motor, gas valve, control board. Larger jobs (heat exchanger crack, full draft inducer replacement) run higher and sometimes tip the math toward replacement on older units. We diagnose and quote flat rate before starting.
